WALTHAM — Through two games of this series the Celtics have been called for 56 fouls to the Cavaliers 33 and they have shot 39 free throws compared to 69 for the Cavs.

With the NBA cracking down on coaches and players who speak ill of the way the game is called, the Celtics have refrained from voicing their displeasure with the discrepancy. Doc Rivers adhered to that when he was asked about it at practice Wednesday.

“We’re going to play the way we play and we’re not going to change the way we play,” Rivers said. “We have to do a better job of doing it without fouling. And we have to do a better job, somehow, of drawing some fouls on them.”

Pressed further, Rivers said, “We have to be more aggressive offensively. We have to attack more. It is something we want. As well as we’ve played, the low free throw attempts for us, we have to get to that line more.”

There’s a subtle message in there. The Celtics have played well and usually the team that plays better is rewarded with more calls. The Cavs may have set an unofficial record by going more than 19 minutes without getting whistled for a personal fouls in Game 2.
